Highest 6.2 times biomass was enhanced in suspension cultures of nodal/internodal callus supplemented with threefold total sulphate. Picloram 8.28 mu M along with BAP 8.88 mu M enhanced 295.05 times inophyllum A in suspension cultures of leaf callus whereas IBA 14.70 mu M along with BAP 4.44 mu M in suspension cultures of leaf callus enhanced 1065 times inophyllum B. IBA 4.90 mu M alone in suspension cultures of nodal/internodal callus enhanced maximum 616 times inophyllum C. Only IBA 9.80 mu M in suspension cultures of leaf callus enhanced 23.22 times inophyllum P. Variation in nitrate and sulphate had maximum positive influence on expression of inophyllums A and C and vitamins had maximum positive influence on expression of inophyllums A, C and B.

The optimum timing for elicitor introduction was found to be the 10th day after initiating the suspension cultures. Cadmium as abiotic elicitor in suspension cultures of stem callus was found best to elicit maximum production of inophyllums A, C, and calophyllolide while cadmium in suspension cultures of leaf callus was found best for eliciting maximum production of inophyllums B and P. Inophyllum D was the only dipyranocoumarin whose highest production was achieved when 1.0 mM chromium was used as abiotic elicitor in suspension cultures of stem callus. Out of the three abiotic elicitors used, none could result biomass growth. Only incorporation of CaCl(2) in suspension cultures resulted biomass growth. A maximum of 35.26-fold biomass growth was achieved when suspension cultures of stem callus were incorporated with 2.0 mM CaCl(2). CaCl(2) was noted to have no positive influence on production of most of the dipyranocoumarins under study.</p>10aAbiotic elicitation10aCalophyllum inophyllum10adipyranocoumarins10aHeavy metals10aSuspension culture1 aPawar, Kiran, D.1 aThengane, Shubhada, Ratnakar  uhttp://library.ncl.res.in/content/influence-abiotic-elicitation-production-dipyranocoumarins-suspension-cultures-calophyllum-0
